Short and anecdotal, this one. Perhaps I need a new category - TMI (too much information) I live in a small, poorly insulated house with a wood stove for heat. The wood stove is rather small and fits in a stone fireplace. The stove is also fairly new and efficient but really doesn't hold a fire all night. So.... In the winter when the nights are cold I have a “system”. In order to insure that I wake up at least once during the night to feed the fire I make sure to drink lots of water before I go to bed. The ramifications of neglecting to do this are chilling. And it keeps me nice and healthy too.
